The spelling of "Engraff" is rather unusual and may present a challenge to those unfamiliar with it. The word is pronounced /ɪnˈɡræf/ and originates from the Old English word "ingraefan," meaning to graft or insert. The spelling with two "f's" rather than one is likely a result of the word's Germanic origins. Despite its uncommon spelling, Engraff remains an important term in horticulture and refers to the process of grafting trees or plants.
